I dont really think there is a problem with the buttons being sunk in and if anything it protects the power button from accidently getting hit by someone sitting on it or not paying attention and turning off you Wii.

i have had that happen a few times before i got the gloves and it was a pain in the ass. seriously bowling the best game i have had, still bowled that good, and my girlfriend hits the power button some how and i lose my game. sucked more then "sunk in" buttons
